The performance of distributed key-value stores is usually dependent on its underlying network, and have potential to improve read/write latencies by improving upon the per- formance of the network communication. We explore the potential performance increase by designing an experimental in-network cache based on NetCache in the switch data plane for the distributed key-value store DXRAM, and placing it on a programmable switch that connects the peers in a DXRAM storage cluster. To accomodate DXRAM which uses TCP for its transport protocol, we also design a TCP flow state translator for the cache and implement an experimental version of this cache design. Benchmark runs with the cache show that best-case item read latency for DXRAM is reduced to approximately half and prove the potential performance gain that can be expected once a proper cache is designed and implemented.
